arm: Remove __builtin_arm_uqsub8 usage on string-fza.h
The __builtin_arm_uqsub8 is an internal GCC builtin which might change in future release (the correct way is to include "arm_acle.h" and use __uqsub8 ()). Since not all compilers support it, just use the inline assembler instead. Checked on armv7a-linux-gnueabihf. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
